V i s'oiaims. (ci. 24o- 53) This invention relates to alamp structure.

One object of this invention is "to includev in a lamp structure a pivotor hinge structure whereby a portion thereof may serve as a pedestal,table or like type support for the lamp' and may also serve asa hangingbracketfor wall, etcetera, engagement for pin-up support for thelamp.

lAnother' object of the invention is to provide ashield for the bulbofthe lamp to eliminate direct glare therefrom when used-as either type oflamp. 4

Another object of the invention'is to provide a-shade support,independent of the bulb, which clampingly supports a shade so same willnot be displacedetc., by casual contact therewith when the lamp is usedas either type. Y

Another object of the invention is to provide in a lamp structure aninterlocking relation 'whereby a simple', rugged and-relativelyimmovable connection is obtained between parts-'of the structure. 'V

A further cbjectof the invention is to provide arlamplstructure capableof ready association of parts and sc formed that certain cooperatingrelationship exists therebetween, facilitating packaging in minimum`bulk. or` volume containers.

The ychief featureof the, invention resides in the formation of a lampstructure whereby each of the aforesaid objects may be accomplished.

Other objects and features will be set forth more fully hereinafter.

The full nature of the invention will be understood fromthe-accompanying drawing Yand the following. description and claims:

Inthe drawing, Y

Fig. f f is a central sectional viewof a shaded multiple type lampstructure, they bulb and socket being shown in velevation, full linesillustratinguse asa table or pedestal type ylamp and vdotted linesindicating the adjustable lower portions in the wall or "pin-upposition, and the shade and supporting arms prior to association. Fig. 2is a transverse sectionalview taken on' .line 2 2 of Fig. 1 and in thedirection of the shells 25 and 26.

tainer structure with the disassembled lamp therein.

Fig. 6 is a plan sectional view of the box bottom.

In the drawing, I0 indicatesva base element provided with a peripheralskirt portion II with .an inwardly and upwardly directed ange por-`bossed or dished upwardly as at I6 forming the central plate portionI9, which is centrally apertured as at 20, the aperture being hereinVsquare inv outline.

In spaced relation thereto, there is a tubular structure having aperipheral frame portion or skirt 2| and an upwardly and inwardlydirected portion 22 of ornamental character, the latter at its upper endextending inwardly as at 23 to form a bearing, said bearing beingapertured as at 24. V

Herein there are illustrated two hemispherical The shell 25 has anoutwardly directed rim portion 2l and the shell 26 has an inwardlydirected cooperating rim portion 28, the two confronting each other andbeing so arranged that the same interlock and thus 'are prevented fromdisengagement or separation, yet permit of relative rotational movementabout their confronting outer edges.

The'hernispherical'portion 25, offset from the Vcentral axis, isapertured as at 29 and herein said aperture registers with the aperture24 in the A similarly outlined tubular clamping structure is indicatedas at 3i), see Fig. 2; and the same Fig. 3 is a sectional view takenOnline 3-3 of v Fig. 5 and in the direction of the arrows.

Fig. 4 is a top pian view of the combination i shield and shadesupporting arm structure, a portion being broken away to show theconnection therebetween in greater detail.

Fig. v5 is'a central .sectional view .of a con'- i extendsthrough atubular spacing member 3|, to

29 and 20 aforesaid,

Each end of this tubular clamping means or member is provided withoutwardly and laterally :directed extensions 32 located within the shell25 V54, split as at 55.

and extensions 33 at the lower end and located within base l0. Thus, theshell 25 is definitely located and rigidly connected to the base l andin a predetermined relationship. The axis of rotation between the twohemispherical shells is such that it bears a definite relationship tothe opening I4 when the lamp is positioned for pin-up purposes and withrespect to the opening l5, which then would lie beneath the opening i4for current supply purposes by means of the cord I6, the same beingshown clearly in Fig. 1 by the dotted lines.

Referring to the tubular standard 3 l the same, as shown most clearly inFig. 2, consists of an annularly corrugated member, the corrugationsbeing indicated by the numeral 34. Herein tongues 35 are provided byforming openings 36 in the base portion l0 adjacent or coincident withthe oiiset portion i8 and these upwardly directed tongues, of whichthere are at least two, diametrically positioned, or a plurality inarcuately spaced relation, serve to centrally locate the tubularstandard 3l and prevent lateral displacement thereof relative to thebase and prevent relative rotational movement relative to said base.

It will be notedsee Figs. 1 and .2-.that the tubular clamping means 30consists of .a sheet of metal formed into polygonal outline Yand having-aV closed relationship at the adjacent edges 38a.

At opposite ends, each side of this tubular-member is provided withlateral enlargements, ,the enlargements initially being coplaner withthe supporting side and thereafter being deformed laterally in theassembling and clamping operation incident fto uniting the shell 25 andthe base lll to form a rigid lower Vbody portion of lamp structure.

Herein the 4upper shell :2:5 is apertured w at 4.9 and said aperture isdened by an outwardly .dlrected collar portion lll, the same fbeing:turned upwardly and laterally as at '42 .to lock-thereto the baseportion 43 of a lamp socketstructure, generally indicated by thenumeral'llli and having the lswitch operating member 45, if desired, thebulb receiving portion lit :andthe external thread adjacent thereto asat 111.' This ybulb Socket yportion i6 is adapted to Vsupporta bulb t3,the current to which is controlled by switch Ycontrol member |35 andsaid current is supplied through said socket by the cord |15 which, aspreviously stated, extends upwardly through the tubular clampingstructure 3E, Which furthermore extends through the two semi-circularconnecting body portions.

The numeral Ed indicates a shade of frustum type and herein of frustoconical shape, the lower edge being indicated by the numeral I. There isprovided a hub member 52 which is internally threaded to mount upon the.threaded portion 41 oi the vlamp bulb socket and the portion 52includes an outward extension or annular ange portion '53, and thelatter at spaced points extends `outwardly and terminates in grippingarms Herein-see Fig. 4-three of said tubular sockets are provided andeach Yreceives the inner end of a spring rib or arm 56 that bears at itsinner end 51 -against the surface 58 .of 'theinternally threaded portion52.

.Each arm 53 considerably remote from the socket received end, includesan angularly directed portion V59, the same terminating at its free endin the hook portion 50. In Fig. 1 the full lines `indicate these armportions 56 which are substantially .horizontal when the lower end 5| ofthe shade is seated in the hook portion 60 and the cooperation is suchthis arm portion is then under compression and tends to extend and thusdoes clampingly engage and seat the lower end 5| of the shade. Thedotted line positions of these parts show their relative relationshipbefore the shade and arms are associated together. When so associatedtogether, the two are rigidly connected together and casual displacementor accidental separation is prevented.

When the lamp structure is utilized as a wall or pin-up lamp, it isquite apparent that direct glare from the bulb 48 may be exceedinglyannoying. Also, for mantle purposes, this glare may be annoying. Whenthe lamp is utilized as a mantle lamp, it is of table lamp type. In bothof these. instances, such glare is substantially prevented by theprovision of a shield 62- see Figs. 2 and Jie-which is of somewhatfrustoconical type and its inner smaller and lower end is deiined by acollar portion 63. This collar portion 63 is pressed upon by the .outer:rim of `portion .53 of the hub arrangement of the .lamp :shade .supportstructure. The shield `collar 53 is notched -at -54 to accommodate Varms56 and sockets 54.

Reference now lwill be had to Figs. 5 and 6 `wherein lfurther utility ofthis lamp structure is illustrated. In this gure, the numeral -10indicates side walls of a container, 1l the bottom and 12 the top.Bottom portion 13 is centrally ,apertured as at 14 and radially slit asat 15 to form upwardly directed tongues 16. These tongue portions areturned upwardly andthe .base -Ill of the lamp is yseated in the recessthus formed. The tongues then are .turneddownand 4the 4inner .edgeslii-,frlctionally .engage the tubular pedestal portion of the lamprbody.thelampat its Ylower end is centrally located and .rigidly anchored inthe container. Y

The shade'structure then ,is placed in -the container. Thereafter thereis inserted a partition member 18 having laterally and upwardly directedanges 19, the same frictionally vengaging the side walls 10. T-hispartition 1B is 4apertured las --atYBll-see Fig. B-and the same islaterally enlarged as at 8l to per-mit the passage .of the bulb socketand the switch member, respectively, so that the partition 18 may bearupon the upper edge of the .shade and immediately adjacent ,thesocketconnection to .thesphere The unltary shade support and shield thenisinverted and screw threaded on to the upper end of the bulb socket sothat the free `ends ,0 f the arms Vextend outwardly and upwardly. Ifdesired, the Vouter and larger edge 4of the shield may 4engage thepartition '18. This partition r,naturallt Plievents the upper end of thelamp 'body from lat eral displacement vso that the lamp-body is rigidlymounted in the `container and the shield vis'similarly mounted. f

"The lower edge^5l of the 'lamp ishade may be of such diameter VthatIthe insidesurfaces of 'the container-side walls Llil may be tangentialthere- 1Vto, thus `denite'ly locating r'the shade and ,preventingdisplacement thereof. The height -of `the shade also may :be fsuchalthough foptional `herein, thatiits upper edge is engaged by thepartition, as herein illustrated, when its lower edge L51 is-supported'by the member .13 .of the bjottom 1l, thus `definitelylocating ythe `shade. 'The arm 'portionsas previously stated, aredirected .outvwardly `and-.herein 11pwardly, =since rthezshadesupport:and shieldzunit are inverted.

The entire structure, thereuoreI when packaged vfor transportation.storage. and lthe Vis .-ar-

ranged in a very compact relationship and is adapted for reception bythe main volume type container. The partition 18, as stated, preventspenetration ofthe lamp shade by the arm portions. The cord and the likepreferably is carried upwardly and extends through oneV of the openings8|, see Fig. 3, in the partition and is suitably looped into a compactform and these loops are held together by a rubber band in aconventional manner, so that the supply line and plug is formed into acompact unit and thus, does not have any contact with the lamp bodyproper or the shade, the same being below the partition. It is to beunderstood the illustrations herein and the particular description aredirected to but one specific embodiment of the invention.

While the invention has been illustrated and described in great detailin the drawing and foregoing description, the same is to be consideredas illustrative and not restrictive in character,

The several modiiications described herein as well as others which willreadily suggest themselves to persons skilled in this art, all areconsidered to be within the broad scope of the invention, referencebeing had to the appended claims.
